Cable ties consists of a sturdy Nylon tape with an integrated gear rack, and on one end a ratchet within a small open case. Once the pointed tip of the cable tie has been pulled through the case and past the ratchet, it is prevented from being pulled back; the resulting loop may only be pulled tighter, also allowing several cables to be bound together into a cable tree. Most commonly, cable ties are perfect for binding several electronic cables or wires together, and to organize cables and wires.
